Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly and completely understood, the technical solutions in the embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.
The invention provides a liquid crystal device, a preparation method thereof and a display device, which are used for providing the liquid crystal device, and the liquid crystal device saves the number of substrate plates for manufacturing the liquid crystal device, thereby reducing the manufacturing cost of the liquid crystal device and simplifying the structure of the liquid crystal device.
The following describes in detail specific embodiments of a liquid crystal device, a method for manufacturing the same, and a display device according to embodiments of the present invention, with reference to the accompanying drawings.
The thicknesses and shapes of the various film layers in the drawings are not to be considered true proportions, but are merely intended to illustrate the present invention.
Referring to fig. 1, an embodiment of the present invention provides a liquid crystal display device, which includes a plurality of liquid crystal panels 100 stacked one on another, and a substrate is shared between adjacent liquid crystal panels 100; each liquid crystal panel 100 includes an array substrate 01 and an opposite substrate 02 which are oppositely disposed, and a liquid crystal layer 03 located between the array substrate 01 and the opposite substrate 02. In fig. 1, a liquid crystal device includes two stacked liquid crystal panels 100 as an example, and in the adjacent liquid crystal panels 100, an array substrate 01 and a counter substrate 02 share a substrate. Of course, when the liquid crystal display device includes two or more stacked liquid crystal panels 100, the liquid crystal panels 100 are stacked in sequence like that shown in fig. 1, and the description thereof is omitted.
Since the substrate base plate 10 is shared between the adjacent liquid crystal panels 100, the number of the substrate base plates is reduced, the cost for manufacturing the liquid crystal device is reduced, and the structure of the liquid crystal display device is simplified.
In the liquid crystal display device provided by the embodiment of the invention, in order to reduce light leakage of the liquid crystal panel 100, an optical compensation structure may be disposed on the liquid crystal panel 100. Specifically, as shown in fig. 2, fig. 2 exemplifies that the liquid crystal display device includes two stacked liquid crystal panels 100. In each liquid crystal panel 100, a polarizer 05 and a transparent film 06 may be disposed on a side of the opposite substrate 02 facing away from the array substrate 01, wherein the transparent film 06 is located on a side of the polarizer 05 facing away from the opposite substrate 02 to isolate the liquid crystal in the liquid crystal layer 03 from direct contact with the polarizer 05. The polarizer 05 may be a polyvinyl alcohol (PVA) based polarizer, and optically compensates the liquid crystal panel 100 to reduce light leakage. The transparent film 06 may be an organic film or an inorganic film. Preferably, the transparent film 06 may be a Polyimide (PI) film, or other transparent film having a relatively high transmittance.
For example, when the liquid crystal display device includes two liquid crystal panels stacked, the two liquid crystal panels stacked include a first array substrate 01, an opposite substrate 02, and a second array substrate 01, which are sequentially disposed; the first array substrate 01 and the second array substrate 01 include a color filter and a black matrix. The opposite substrate 02 comprises a first polarizer 05 and a first transparent film 06 on the side of the opposite substrate 02 away from the first array substrate 01; the first polarizer 05 is located between the first transparent film 06 and the opposite substrate 02. Alternatively, the opposite substrate 02 includes a second polarizer 05 and a second transparent film 06 on a side of the opposite substrate 02 facing the first array substrate 01, wherein the second polarizer 05 is located between the second transparent film 06 and the opposite substrate 02.
When the liquid crystal display device provided by the embodiment of the invention is implemented specifically, the polarizer 05 may also be disposed on a side of the opposite substrate 02 facing or departing from the array substrate 01 through a high temperature process. For example, a nano-imprint technology is adopted to manufacture a nano-grating structure on one side of the opposite substrate 02 facing or deviating from the array substrate 01 to form the polarizer 05, so that the commonly-used externally-adhered PVA-based polarizer which is easy to be damaged by high temperature can be avoided as much as possible, and the new compensation performance of the polarizer 05 can be ensured as much as possible. In a possible embodiment, the nano-grating structure is preferably a nano-aluminum film grating array. Further, in this case, since the substrate is shared between the adjacent liquid crystal panels 100, when a portion of the substrate is formed by a high temperature process, the performance of other layers of the substrate may be affected. Therefore, in the embodiment of the present invention, the array substrate 01 may be a boa (bm On array) substrate or a coa (color Filter On array) substrate, that is, a portion of the film layer 04 that needs to be processed at a high temperature is located On the array substrate 01. This allows the films on the opposite substrate 02 side, such as the polarizer 05, to avoid high temperature processes, thereby avoiding performance degradation or failure of some of the films already formed on the display panel.
In a possible embodiment, the first array substrate 01 further includes a first protective layer covering the color filter and the black matrix, and a third polarizer 05 located on a side of the first protective layer away from the first array substrate 01. The second array substrate 01 includes a second protective layer covering the color filter and the black matrix, and a fourth polarizer 05 located on a side of the second protective layer away from the second array substrate 01. In the embodiment of the invention, a nano-grating structure can be manufactured on one side of the first protective layer, which is far away from the first array substrate 01, by adopting a nano-imprinting technology to form the polarizer 05.
When the liquid crystal device provided by the embodiment of the invention is implemented specifically, the liquid crystal layer 03 can be filled with non-blue phase liquid crystal. If the liquid crystal layer 03 is filled with a non-blue phase liquid crystal, it is necessary to align the substances filled in the liquid crystal layer 03. Specifically, referring to fig. 3, fig. 3 also exemplifies that the liquid crystal device includes two stacked liquid crystal panels 100, and in each liquid crystal panel 100, the array substrate 01 includes a first alignment layer 07 in contact with the liquid crystal layer 03, and the opposite substrate 02 includes a second alignment layer 08 in contact with the liquid crystal layer 03. The first alignment layer 07 and the second alignment layer 08 may align liquid crystal molecules in the liquid crystal layer 03 in a fixed direction. In a possible embodiment, the first alignment layer 07 and the second alignment layer 08 are both horizontally and/or vertically oriented alignment layers, or the first alignment layer 07 and the second alignment layer 08 may also be vertically oriented alignment layers.
In a possible embodiment, the non-blue phase liquid crystal may be a positive liquid crystal, a negative liquid crystal, or a combination of a reactive self-coordinating monomer and a liquid crystal.
When the liquid crystal device provided by the embodiment of the invention is implemented specifically, the liquid crystal layer 03 can be filled with a blue phase liquid crystal material. If the liquid crystal layer 03 is filled with blue phase liquid crystal, the array substrate 01 may not include the first alignment layer 07 in contact with the liquid crystal layer 03, and the opposite substrate 02 may not include the second alignment layer 08 in contact with the liquid crystal layer 03.
It should be noted that the liquid crystal device provided in the embodiments of the present invention may be applied to the display field, for example, may be manufactured into a liquid crystal display panel, and may also be applied to the sensor field.
Based on the same inventive concept, an embodiment of the present invention further provides a method for manufacturing the liquid crystal device, as shown in fig. 4, the method includes the following steps:
s401, forming a first array substrate 01, an opposite substrate 02 and a second array substrate 01, wherein a color filter film and a black matrix are formed on the first array substrate 01 and the second array substrate 01 by adopting a high-temperature process;
s402, aligning the first array substrate 01 and the opposite substrate 01 to each other;
s403, forming a first polarizer 05 on one side of the opposite substrate 01, which is far away from the first array substrate 01, by adopting a low-temperature process;
s404, forming a first transparent film 06 on the side, away from the opposite substrate 02, of the first polarizer 05 by adopting a low-temperature process;
s402, the counter substrate 02 on which the first transparent film 06 is formed and the second array substrate 01 are aligned.
Specifically, in the above manufacturing method provided by the embodiment of the present invention, the Array substrate 01 is first manufactured, and all the components such as Array, color filter, black matrix and the like which require a high temperature process may be manufactured on the transparent substrate, for example, a common electrode is formed on the transparent substrate, an insulating layer is formed on the common electrode, a pixel electrode is formed on the insulating layer, including forming the black matrix and a pixel region, a color filter is formed on the pixel region, a flat protective layer is formed on the color filter, and a spacer is formed on the flat protective layer, so as to obtain the Array substrate 01. The array substrate 01 and the opposite substrate 02 are coupled to form one liquid crystal panel 100. In a possible embodiment, after the color filter and the black matrix are formed on the first array substrate 01 using a high temperature process, a first protective layer covering the color filter and the black matrix may be further formed on the first array substrate 01. After the color filter and the black matrix are formed on the second array substrate 01 using a high temperature process, a second protective layer covering the color filter and the black matrix may be further formed on the second array substrate 01.
After obtaining the liquid crystal panel 100 after cell pairing, another counter substrate 02 is formed by using the back surface of either side substrate of the liquid crystal panel 100, and another liquid crystal panel 100 is formed after cell pairing with another array substrate 01. Specifically, a low temperature process may be adopted to attach the polarizer 05 and the transparent film 06 in sequence on the back of either side substrate of the liquid crystal panel 100 as the counter substrate 02 of the other liquid crystal panel 100. An Array, COA, or BOA layer is formed on another substrate as the Array substrate 01 of another liquid crystal panel 100, that is, a part of the film layers that need to be formed by the high temperature process is formed on the Array substrate 01 of another liquid crystal panel 100, so as to prevent the high temperature process from affecting the performance of other film layers of the substrate, such as the polarizer, as much as possible.
Alternatively, the polarizer 05 may be formed by fabricating a nano-grating structure, such as a nano-aluminum film grating array, on the inner side or the back side of the common substrate by a high temperature process, such as a nano-imprint technique. For example, a nano-imprint process is used to form a nano-grating structure on the side of the first protection layer away from the first array substrate 01, so as to form the polarizer 05. And forming a nano grating structure on one side of the second protective layer, which is far away from the second array substrate, by adopting a nano imprinting process so as to form the polarizer. Specifically, the nano-grating structure can be adjusted in the process steps of the film layers related to the common substrate according to design requirements, for example, the structure is directly arranged on a glass substrate, or the structure can be arranged in the processes of the TFT layer and the opposite layer respectively corresponding to the upper side and the lower side of the common substrate, and the front side and the rear side of the structure are filled with insulating films such as OC, PVX and the like. In this case, the array substrate 01 of the liquid crystal panel 100 may be a BOA substrate or a COA substrate, that is, the portions of the film 04 that need to be processed at a high temperature may all be located on the array substrate 01.
The liquid crystal filled in the liquid crystal panel 100 may be non-blue phase liquid crystal. If the liquid crystal panel 100 is filled with non-blue phase liquid crystal, in the above-mentioned preparation method provided in the embodiment of the present invention, the first alignment layer 07 may be fabricated on the side of the array substrate 01 facing the liquid crystal layer 03 and the second alignment layer 08 may be fabricated on the side of the opposite substrate 02 facing the liquid crystal layer 03 through a low-temperature PSVA process or a low-temperature SA-FFS process. For example, when the first alignment layer 07 and the second alignment layer 08 are manufactured by using a low-temperature PSVA process, a cross-shaped electrode or other multi-domain electrodes are used in a single pixel of the array substrate 01 to prepare multi-domain partitions, which helps to reduce the problem of large-angle light leakage in the VA mode. In the process segment of forming the alignment layer by PSVA low-temperature photo-alignment curing, different voltages are connected to the electrodes of the array substrate 01 and the counter substrate 02 of the liquid crystal panel 100 to help the alignment to be stable, and then the polymerizable monomer is cured by illumination to deposit and form the low-temperature alignment layer. For another example, the alignment layer is patterned using two uv light passes. The first time of adopting polarized ultraviolet light helps the liquid crystal molecules in the liquid crystal layer 03 to orient and polymerize with the reactive monomers to form an alignment basic layer, and the second time of adopting ultraviolet light helps the alignment layer to solidify and stabilize. The first alignment layer 07 and the second alignment layer 08 are implemented by a low temperature process, so that performance degradation or failure of the polarizer 05 due to a high temperature process is prevented as much as possible. In one possible embodiment, the non-blue phase liquid crystal may be a positive liquid crystal, a negative liquid crystal, or a combination of a reactive self-coordinating monomer and a liquid crystal.
The liquid crystal filled in the liquid crystal panel 100 may be a blue phase liquid crystal, and in this case, the first alignment layer 07 and the second alignment layer 08 do not need to be formed.
In the above, only taking the preparation of the liquid crystal panel 100 including two stacked layers as an example, the embodiment of the present invention may prepare the (N + 1) th liquid crystal panel 100 by sharing the substrate of the nth liquid crystal panel as the opposite substrate 02 of the (N + 1) th liquid crystal panel 100 on the basis of preparing the liquid crystal display device including the N liquid crystal panels 100 by using the preparation method similar to the above-described preparation method including the two or more stacked liquid crystal panels 100, and repeated parts are not repeated. According to the preparation method of the liquid crystal display device, the substrate sharing the liquid crystal panel 100 and the other array substrate 01 are paired to form the other liquid crystal panel 100 on the basis of the liquid crystal panel 100 obtained by pairing the boxes, the alignment precision of the box process section is better than that of the attaching section, and the technical risks of Moire, Newton's rings, transmittance reduction and the like can be reduced.
Based on the same inventive concept, embodiments of the present invention further provide a display device including the liquid crystal display device according to any one of the above embodiments of the present invention. If the display device needs to display color effect, a color filter may be disposed on any layer or multiple layers of any panel of the liquid crystal display device, or other color devices such as quantum dot films may be disposed. The display device may be: any product or component with display and touch functions, such as a mobile phone, a tablet computer, a television, a display, a notebook computer, a digital photo frame, a navigator and the like. The implementation of the display device can refer to the above embodiments of the liquid crystal device, and repeated descriptions are omitted. Because the adjacent liquid crystal panels in the liquid crystal device share the substrate, the quantity of the substrate is saved and the cost for manufacturing the liquid crystal device is reduced. The array substrate 01 may be a BOA substrate or a COA substrate, that is, a part of the film layer 04 that needs to be processed at a high temperature is located on the array substrate 01. This makes it possible to prevent the films on the side of the counter substrate 02, such as the polarizer 05, from being hot and cold sealed during the subsequent (multi-layer) cell-forming process, thereby preventing the performance degradation or failure of some of the films already formed in the liquid crystal device. If the liquid crystal display device is a multilayer structure and the polarizer 05 is a PVA type polarizer, a low temperature cell alignment process may be employed. If the liquid crystal display device is a multi-layer structure, the polarizer 05 may be a nano-grating structure if a high temperature cell-to-cell process is employed.
It will be apparent to those skilled in the art that various changes and modifications may be made in the present invention without departing from the spirit and scope of the invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include such modifications and variations.
